synthesis, chemical characterization and functional evaluation are reported for dichloro(6-aminoethylaminopurine)platinum(II) and dichloro(6-hydroxyethylaminopurine)platinum(II) and dichloro(6-hydroxyethylamethylaminopurine)platinum(II) ( i.e. Pt(6-AEAP), Pt(6-HEAP) and Pt(6-MHEAP) newcomplexes of platinum(II). Certain reaction conditions favored the formation of the tripurine platinumcomplex, but the monopurine
The cyclization of N6‐(ω‐hydroxyalkyl)adenines with a N6H‐group leads to N6,N1 ring closure regardless of the method of the cyclization that was used. Five‐membered to eight‐membered rings were obtained using NBS/PPh3; however, under Mitsunobu conditions, the eight‐membered fused purine was not formed. Surprisingly, the cyclization of N6‐methyl‐N6‐(4‐hydroxybutyl)adenine only leads to N6,N7 ring closure
